  1. Which statement is TRUE?
    1. -3 > -1
    2. -5 < -2
    3. -4 > 0
    4. -1 < -6
  2. Plot these integers and write them in order from greatest to least: -8, 4, -3, 1, -1, 6
  3. Compare each pair of integers using < , > , or =.
  4. Find the Comparison Error
    1. Step 1: Problem — Compare -3 and -8. Which is greater?
    2. Step 2: Student thinking — 8 is bigger than 3, so -8 must be greater than -3
    3. Step 3: Student answer — -8 > -3

    Which step has the mistake? Explain it and write the correct work.
